This helps by letting us add checks for when the runner has already
been set. There is documentation saying you can set
-DBOARD_DEBUG_RUNNER at the command line and have it take effect,
which turns out not to be true for a large number of boards.
A status message helps the user debug.
(We'll address the existing in-tree boards in the next patch.)
